Abstract

Um die beim Walzen von Flachprodukten geforderte Oberflächengenauigkeit bzw. -güte zu erzielen, ist eine Führung der Arbeitswalzen im Walzspalt auf besonderen Bahnkurven erforderlich. Hierzu werden bei den üblicherweise angetriebenen Arbeitswalzen Führungsstücke verwendet. Die Konstruktion für die Walzenantriebe ist sehr aufwendig und die Elemente für die Walzspaltverstellung hohem Verschleiß unterworfen. Der Erfindung liegt die Aufgabe zugrunde, mit einfachen konstruktiven Mitteln die Führung der Arbeitsrollen im Walzspalt so zu gestalten, daß Verschleiß weitgehend vermieden wird. For the rolling of flat products required surface accuracy or quality achieve is a guide of the work rolls in Roll gap on special trajectory curves required. For this purpose, the usually driven work rolls Guide pieces used. The construction for the roller drives is very complex and the Elements for high roll gap adjustment Subject to wear. The invention lies based on the task with simple constructive means leading the To design work rolls in the nip so that wear is largely avoided.

Diese Aufgabe wird dadurch gelöst, daß in einem Walzgerüst nicht angetriebene Arbeitswalzen (5) in angetriebenen Stützkörpern (4,4a,4b) radial beweglich gelagert sind und mit diesen umlaufen. Dadurch vereinfacht sich die Konstruktion wesentlich. Sie stützen sich auf Zwischenringen (6) ab, die exzentrisch auf Achsen (7) gelagert sind. Durch ein Verdrehen dieser Achsen (7) mittels Kulissen (16), Führungsrollen (14) und Hebeln (15) wird eine weitgehend verschleißfreie Walzspaltverstellung erreicht. This object is achieved in that Roll stand non-driven work rolls (5) in driven support bodies (4,4a, 4b) radially movable are stored and circulate with them. Thereby the construction is significantly simplified. They are supported on intermediate rings (6) that are mounted eccentrically on axes (7). Through a Turning these axes (7) by means of links (16), Guide rollers (14) and levers (15) will be largely wear-free roll gap adjustment achieved.

Walzgerüste entsprechend dem Erfindung werden vorteilhaft für die Herstellung von allen Arten von Flachprodukten (3) mit hohen Oberflächenanforderungen eingesetzt. Roll stands according to the invention advantageous for the production of all Types of flat products (3) with high Surface requirements used.
